  1. Support the same PartitionKey/RowKey sorting as Azure Table Storage

    The lack of this feature in Table API prevents a lot of apps to migrate from Azure Table storage to Cosmos DB because this is the only sorting functionality in tables and apps are actively using this feature.

    We have reviewed this request.

    While we are API compatible with Table storage we do not precisely match every behavior. Sorting is one of those. We do not have any current plans to support this but will put on our backlog.

    For a complete listing of where our implementation diverges from Table storage please see this article below.

    Thank you.

  4. Add Callback handler based on partition key, so polling is not needed/charged RUs


    1. ChangeFeedProcessorBuilder does not support subscribing only to certain PartitionKeys, so it'd be great if you supported that.


    2. If not, I can get by with GetChangeFeedIterator and manual polling (pull model), but that's in preview, so please release that officially.


    3. I believe even in #1, we are charged RUs for polling behind the scenes (correct me if I'm wrong.) So idle host instances are constantly consuming RUs. Is it possible to trigger Cosmos to call the registered callback handler only when something happens on the change feed --for the specified partition key. A trigger replaces polling. Then only charge RUs for…

  6. Be able to add an alias containing a space in Cosmos SQL

    It would be nice to be able to use syntax such as

    select 1 as 'hello world' from c

    {
    'hello world': 1
    }

    to be able to select an alias containing a space. Resulting in the json attribute containing a space. Currently this gives a

    'Syntax error, incorrect syntax near ''hello world''.

    exception

    Hello and thank you for your suggest. We actually do support this but it’s rather complex to do it. We will add this to our back log to include in a future semester work item. For now I can provide you an example using our nutrition dataset from our docs on how you can write a query that does this.

    SELECT VALUE {’hello world’ : c.id, ‘words with spaces and all the characters I want !;28#)(*@#’: c.version}
    FROM c

    It produces:
    [
    {
    “hello world”: “10181”,
    “words with spaces and all the characters I want !;28#)(*@#”: 1
    },
    {
    “hello world”: “11987”,
    “words with spaces and all the characters I want !;28#)(*@#”: 1
    },
    {
    “hello world”: “07961”,
    “words with spaces and all the characters I want !;28#)(*@#”: 1
    },
    {
    “hello world”: “10180”,
    “words with spaces and all the characters I want !;28#)(*@#”: 1
    },
    {
    “hello world”: “11986”,…

  7. Add Select * without X capability (project-away)

    Add Select * without X capability (similar to project-away in Kusto). To be able to bring all documents, but without a nested field (that can be large array for example), and this in order to save RUs

  10. Custom role operation for Cosmos DB

    Add operations to read, write and delete of firewall rule for Cosmos DB.
    I could find some other services like SQL, MariaDB and PostgreSQL are having those kinds of operations,
    so I was wondering why Cosmos DB doesn’t.

  11. Expose index transformation progress in the portal

    When going to the Scale and Settings tab I can see in the browser dev tools that the header x-ms-documentdb-collection-index-transformation-progress is returned to the client however this information is not shown anywhere in the UI.

    It would be useful if this information was displayed in the portal (possibly only if less than 100/ a transformation is currently in progress)

    Thanks for your suggestion.

    The index transformation value use see in the header is actually not always an accurate value. There are four replicas in a replica set, each with it’s own copy of the index. When this header is returned it can from a different partition, each which may be at its own percentage of progress during an index rebuild.

    This is something we hope to provide at some point but is on our backlog. Will mark as unplanned for now and change if this moves in the future.

    thanks.

  12. Please add feature that can monitor and set alert about logical partition level data usage

    A single logical partition has an upper limit of 10 GB of storage.
    So, I want to monitor the data usage of each logical partition and set alert about that.
    So, Please add feature that can monitor and set alert about logical partition level data usage.

  14. Move RU throughput allocation from Collections to Database Level and viceversa

  16. To be upto date version of TinkerPop in Azure Cosmos Graph DB

    Apache TinkerPop Graph released v3.4.2 on 28th May 2019, but it seems that Azure Cosmos DB graph is still supporting the v3.2 which was released a year back from today. Azure Cosmos Graph DB should be upto date to support the latest version of Apache TinkerPop Graph.

    TinkerPop v3.4 supports various features like having support of min and max operations on comparable like string.

    Hello and thanks for your request. We support 3.4 from a driver and connectivity perspective but there are a number of features we haven’t implemented such as min and max on non-decimal values.

    These are currently on our backlog to implement so will mark this as unplanned for now which will keep this request open. When this moves off of our backlog we will mark this as planned and update you here.

    Thank you.

  17. Support ST_Buffer Spatial Function

    This is a great function I use frequently in SQL Server. It lets you to generate an area around a point. It makes Radius Searches much easier and flexible. I like to see this in Cosmos DB to make radius searches better.

  18. DATA QUALITY: Please allow for properties to be set using a subquery

    The use case here is incrementing the reply count property on a post vertex. To increment, we have to fetch the post vertex, increment the reply count property within our API, then update the graph with the new property value. Unfortunately, if multiple users reply simultaneously using different instances of our API, the reply count value is set incorrectly. Sending a query to the database and letting the server make the updates by calculating the value would address the issue.
